To (1Z5 to hem 2".- may concern:

Be it "known that I, HUGH E. MARTIN, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Portable Flytraps for Doors, of which the following is aspecification.

My invention relates to portable fly traps for doors; and the objects of my invention are, first, to construct a device that can be placed in a position to intercept the travel of flies, and to have it provided with conical through which flies will crawl and galleries which will lead them into a cage, from which they will not escape; second to have the parts so arranged that all dead flies will be collected in one locality, from which they may be easily removed.

I attain these objects by the mechanism shown in the accompanying drawing in which- Fig. 1, is a partial elevation of the upper end of the trap with the outer screen metal casing removed;

Fig. 2, is a right hand side elevation of the trap with the outer screen metal casing in section;

Fig. 3, is the lower end of Fig. 1, completing the plan;

Fig. 4, is a horizontal transverse section on line 4-4 Fig. 1;

Fig. 5, is an elevation of the trap with the outer screen casing removed therefrom;

Fig. 6, is a right side elevation entire, except galleries 14.

Similar numerals refer to similar parts throughout the several views.

The base frame 1 is cut from a sheet of metal with parallel side edges except where entrance galleries, later described, are to be located and at such points tapering ears 2 extend outward as shown in dotted lines in Fig. 1 and an aperture 3 is cut out of the ears member 2 said ears 2 are then turned upward to a vertical position on the outside lines of the base frame forming approximately semicircular arches 4 through the same and curvilinear notches in the bottom of the base frame. The longitudinal center of the base frame is raised to allow for the thickness of the outer screen casing 5 and a metal binding 6 on the edges of the same. An arched metal band 7 wire arc-hes 8 and 9, and perforated metal head 10, all of the outline form shown in Fig.- 4, are soldered to the base frame as follows; the band 7 near the lower end of the base frame as it is hung vertically on a 'door or screen, the"- arch 8 approximately one-third the 'dlstanc'e'i to the top, the arch 9 two-thirds the distance,

and the head 10 near the upper end. Means for securing the trap to a door 'is' provided b 1%) and below the band 7. ='closu're headll adapted to be inserted in the" band 7 and secured there by a spring latch 12 is provided for purposes hereinafter explained. Tapering wire screen entrance galleries 13 are secured to the ears 2 over the apertures 3 and extend inward andupw'a'r'd on the left side of the trap. Similar entrance galleries" 14are 'disposed'a'nd secured tothe right side" of the trap. A perforated metal partition 15 of rectangular form extends across the base frame near its lower end as shown in Figs. 3, 5 and 6. and is soldered thereto. A duplicate partition 16 is soldered to the base frame a distance below the head 10. An entrance gallery 17 provides a passage through the partition 16 upward, and an entrance gallery 18 a similar passage through the partition 15 downward. 'A screen wire roof 19 the width of the base frame is secured to the partition 15 and 16 at its ends and turned downward a distance on the sides 20 and is solder spot fastened to the ears 2 at 21. Truncated conical wire screen entrance domes 22 provide passages through the back of the base frame, and when holes through a screen door register with the same, allow flies to pass into the trap from the inside of a door. The arched screen casing 5 before mentioned is formed from a rectangular strip of metal wire screen, bound on the edges by a strip of sheet metal '6 folded over and soldered to the same, this casing extends from the lower band 7 to the head 10 and covers the top, forms the sides, and passes under the bottom of the base frame, and the metal binding 6 is soldered thereto. This casing it will be seen by re ferring to Figs. 1-2-3 and 4 entirely covers the trap and is provided with openings registering with the entrance galleries 13 and 14 and in combination with the head 10 and closure 11 encloses the two compart ments 23 and 24. In the compartment 23 the flies can enterthrough any of the entrance galleries 13 and 14 or the domes 22, and out of which they may pass through the entrance galleries 17 or 18 into the arched the base frameextendingyalriove the head compartment24 extending the entire length of the device. When this trap is secured to the outside of a screen door, instead of attempting to pass over it, flies will try to pass through it by means of the entrance galleries 13 or 14 and when inside of the first compartment 23 will travel towards the openings 17 or 18 appearing at the ends, see Fig. 4 and pass into the outerv cage 24 between the roof 19 of the compartment 23 and the casing 5, and after becoming exhausted will fall onto the closure plate 11.

No dead flies will remain on top of the partition16 as the opening and closing of the door will jar them' off, The same construction of trap can be used successfull when placed on a shelf or counter, for files will pass into instead of over it, where ever located. r

Having thus described my invention, and the construction and use ofit, I claim:

In a fly trap, a base plate slightlyraised through its longitudinal center with a plurality of upwardly extending tapered ears along'the edges thereof, arched apertures through the ears extendinga' distance into latch, and means at both ends the base plate, wire entrance galleries secured over said apertures and extending inward and upward, perforated metal parti V 30 tion walls extending across the base plate a distance from both ends, a Wire screen" roof 7 connecting the two partitions, tapering wire entrance galleries secured to and leading outward from the partitions, screen Wire end, a top band secured to the base adjacent the lower end, ascreen wire casing meta-l bound on the edges extending froml the top end Wall to the band, over the top', down the sides, and under the bottom of the base or frame and soldered thereto, a closure plate secured to the bottom of the band by a t v of the device for securing it to a door.
